Chinese J. Chromatogr. 32 (3), 242-247 (2014). Definition of novel molecular connectivity indices and calculation of the indices for 18 chiral hydroxyl acids and amino acids, based on Kier’s molecular connectivity indices and conjugated matrix. Study of the quantitative structure-retention index relationship (QSRR) between the retention index of the chiral organic acids and the chiral connectivity indices by multivariate statistical regression. The best four-parameter QSRR model was set up through leaps-and-bounds regression analysis. The traditional correlation coefficient and the cross-validation correlation coefficient of leave-one-out were given, respectively. The results demonstrated that the model was highly reliable and had good predictive ability from the statistical point of view. From the parameters of the model, it is known that the dominant influence factors on the retention index were the two-dimensional molecular structure characteristics and the space factors such as the chiral characteristics, the flexibility and the puckered degree of the molecules of the chiral organic acids. The results also indicated that the introduced chiral connectivity indices had good rationality and validity for the characterization of the retention indices for the chiral organic acids, thus, provided an effective method for predicting the retention indices of chiral organic acids.
J. Planar Chromatogr. 29, 22-29 (2016). HPTLC of 1-fluoro-2,4-dinitrophenyl-5-l-valine amide diastereomeric derivatives of aspartic acid, cysteine, and histidine on RP-18W with 40–80 % of acetonitrile in water, in 10 % steps. The retention analysis showed that retention of solutes diminished when the mobile phase became less polar.
J. Planar Chromatogr. 31, 105-111 (2018). HPTLC of 13 quinobenzothiazine derivatives on RP-18 with acetone as organic modifier and aqueous TRIS buffer with pH 7.4 and ionic strength of 0.2 M. The contents of the organic modifier in the mobile phase ranged from 40 to 80% in 5 % increments. Lipophilicity parameters were determined for the analysis of structure–activity relationship (QSAR).
Chromatographia 20, 49-52 (1985). Reversed-phase TLC of the metal complexes of meso-tetrakis (p-tolyl) porphine (TTP) on octadecyl-bonded silica with various organic solvents of relative high polarity. Detection by densitometry at 428 nm for MgTTp, 425 nm for VoTTP, 413 nm for NiTTP and CuTTP, 423 nm for ZnTTP and 416 nm for PdTTP and H2TTP.
Chromatographia 25, 643-646 (1988). Investigation of the retention behavior of a group of polycyclic aromatic hydrocarbons having nearly equal ionization potentials but different molecular polarizability values, using reversed-phase TLC on octadecyl-bonded silica with normal alcohols. Discussion of the relationship between retention parameters and molecular polarizabilities of the solutes and solvents.
J. Chromatogr. 499, 361-371 (1990). Studies of reverse-phase retention behavior of 18 benzodiazepine derivatives using TLC on paraffin-impregnated silica with a solution containing 0 – 32.5 Vol-% of acetonitrile in steps of 2.5 % and 6, 12, 30, 60, and 90 mM KHPO4 solution. Detection by their UV absorption spectra. Linear dependence of RM value on organic phase concentration and logarithmically on buffer concentration in mobile phase. Prediction of HPLC retention behavior.
J. Chromatogr. 628, 103-109 (1993). TLC of 29 isomer pairs of 1,2,3,4-tetrahydro-2-naphthol and 3-amino-1,2,3,4-tetrahydro-2-naphthol derivatives on silica or alumina with 6 solvent systems. Detection by different techniques. Discussion of the possibility of two-point contact with the adsorbent in the case of more strongly retained isomers and their edgewise orientation against its surface and the influence of substituents in position 3 of the 1,2,3,4-tetrahydro-2-naphthol ring system on the retention sequence of the respective isomers.
